600 Class Rules


Recommended Posts

I am looking at possibly buying a dedicated 2007 Triumph 675 track bike. In one of the reviews I read it said that the 675 was allowed in competitive races in the supersport class but then was looked at as being an unfair advantage since the fact it has an additional 75cc's.

 

Now is this only for pro level racing such as AMA, WSBK or even for the local trackday races also? I just don't want to spend the money on a track bike I can only do trackdays with and not competitively race it eventually.

Check out the rule book for the series you're interested in and decide from there. There's WERA, CCS and a host of other sanctioning bodies who write the rules for their races. I believe that the 675 tripple is allowed in supersport in most but I could be wrong. I also believe the Ducati 848 is allowed as a twin.

There likely is no one definitive answer for this question. However, I believe 675cc inline triples commonly fit in the "600 class" for racing organizations such as WERA, so my less-than-expert opinion is you're probably ok with the 675. On the other hand, there are almost countless R6's, ZX6R's, GSXR and CBR 600's on the used market if you can tolerate one of those bikes as an alternative.
